Can't see InlineKeyboardMarkup. What did I do wrong?

Question

Java

For the first time I am doing InlineKeyboard for Telegram and InlineKeyboard is not displayed, where is my error?

public class Kino extends TelegramLongPollingBot {
    public Message message;
    public String url;
    public String per;

    @Override
    public void onUpdateReceived(Update update) {
        Message message = update.getMessage();
        this.message = message;
        if (message != null && message.hasText()) {
            if (message.getText().equals("/start")) {
                try {
                    kino(update);

                } catch (Exception ignored) {

                }
            }
        }
    }

    @SneakyThrows

    public void kino(Update update) {
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpGet httpget = new HttpGet("https://videocdn.tv/api/short?api_token=&id=6089");
        HttpResponse response = httpclient.execute(httpget);
        String json = EntityUtils.toString(response.getEntity());


        JsonNode jsonNode = new JsonMapper().readTree(json);
        for (JsonNode data : jsonNode.get("data")) {
            String url = String.valueOf(data.get("iframe_src"));
            this.url = url;
            String per = String.valueOf(data.get("title"));
            this.per = per;
        }
        try {
            SendMessage sms = sendMsg(update.getMessage(), per);
            sms.setReplyMarkup(getinlineKeyboardMarkup());
        } catch (Exception e) {
            System.out.println("Can't send");
        }
    }
    public SendMessage sendMsg(Message message, String text) {
        SendMessage sendMessage = new SendMessage();
        sendMessage.enableMarkdown(true);
        sendMessage.setChatId(message.getChatId().toString());
        sendMessage.setText(text);
        try {
            execute(sendMessage);
        } catch (TelegramApiException e) {
            e.printStackTrace();
        }
        return sendMessage;
    }
    public ReplyKeyboard getinlineKeyboardMarkup()  {
        InlineKeyboardMarkup inlineKeyboardMarkup = new InlineKeyboardMarkup();
        InlineKeyboardButton inlineKeyboardButton = new InlineKeyboardButton();
        inlineKeyboardButton.setText("Смотреть");
        //inlineKeyboardButton.setUrl(url);
        List<InlineKeyboardButton> keyboardButtonsRow = new ArrayList<>();
        keyboardButtonsRow.add(inlineKeyboardButton);
        List<List<InlineKeyboardButton>> rowList = new ArrayList<>();
        rowList.add(keyboardButtonsRow);
        inlineKeyboardMarkup.setKeyboard(rowList);

        return inlineKeyboardMarkup;
    }


    @Override
    public String getBotUsername() {
        return "";
    }

    @Override
    public String getBotToken() {
        return "";
    }
}

If you first send a message, and only then cling to it with a keyboard, then the keyboard will not be sent.
Right here:

// внутри мы вызваем execute, который отправляет сообщение
SendMessage sms = sendMsg(update.getMessage(), per);
// к уже отправленному объекту сообщения мы цепляем клавиатуру
sms.setReplyMarkup(getinlineKeyboardMarkup());
// дальше с переменной sms мы ничего не делаем
